Flashing block



Patented Apr. 9, 1940 1 UNITED PATENT OFFICE ""FLASHINGVBLOCE.. A. v,kvWvilliainlj. F. Garlci,y Chicago, 111.-. Appncatipnfoctober es,iegs'eseriarNo. 231573 g1 claim. `(oil'1mi-26)' y 'Ihis inventionrelates generally .toY roof 'flashing,"and its generalfobject'is toprovide a grooved ashin'g blockl for receiving ashing and especiallycapl or counter-flashing'in the greci/ethereof, the ashing and 'groovebeing shaped for fitting association andthe 'flashing being locked inthe groove by' plastic e'xpansion'matrial such n as asphalt or the like,against casual removal or displacement, as well as disposedinoverlapping relation with base iiashin'g,tro/preventv j any possibilityof leakage'atthefwall"joint,'yet

the flashing lcan be readily removed and replacedA with respect vto thegroove, 'in' theevent of repair 161 to the ,roofv or for otherypurposeaand *without* damage to the flashing. l f

A further object is to provide@ 'fiasriing 'blocuforuse with brick,concrete,prefabricated meta-l ywalls and otherbuilding construction,that is pro.-

vided withalongitudinally arranged groove ex- 'tending therein at anupwardangl'avwith a trough like channel at the inner end; of the groovefor no t only hooking lthe flashing against the front wall of thechannelbut also to .receive the plastic material to cooperatewiththehooked association of theflashing with respect to the groove, toprovide a locking joint `between the blockand flashing.

Another object is tofprovide a iiashing block, brick, strip or the likethat is simple in construction, easy to lay, 'inexpensive tomanufacture, and

extremely efficient in use and service.

l This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accomx Figure 2 is:al-perspective view of a corner block. Figure 3 isa View partly insection illustrating f my flashing block in use for roof flashing andapplied within a block Wall to form apart thereof Figure 4 is a viewillustrating the manner of applying my blockin a concrete wall. y

Figure 5 is a perspective view of my block constructed for use withprefabricatedy metal walls or the like. o

Figure 6 is a perspectiveview of a hanger detail, reference bracket fornsupporting'-my'b'lock withres'pect rto ajiorrn for use of the block ina concrete Wall.

,Referring lto the drawing in detail, and 4pary ticularly to Figure l,`it`wil1 be noted that my l block in the `form of that figure is ofsubstantially .flat rectangular formationI with a groovey I extend- `inglongitudinally of -one'side face 2r thereof and through the end.l faces3, the groovelbeing 'dis-v posed at anupward inclination from the sideface 2 and including la troughl like channel 4 at outer wallk 5 and acurved inner Wall B merging into vthe upper wall cf the inclined portionin curved formatiomas best shown in Figure kI have illustrated the typeof flashing or build- `ing block as shownin Figure 1, in a block wall inFigure`3, and avconcrete Wall in Figure 4, and ,itwill be obvious thatthe block is laid in `the wall of Figure inthe-'usualmanner of layingy@blocks inr Wallsfof that character, and v,with the grooved face`facing lthe roof for receiving the flashing as shown, while in Figure4,4the block is supported Withrespect to the form 'I byfa hanger'bracket ysand a basestrip 9, the latter being secured to the form 1 bynails 4or the like I0. The

hanger bracket is preferablyformed fromV a'single strand of lwire vbentin inverted substantially V- formation to provide an eye I I forreceiving a `nail or the like for securing the same to the form,

l and the arms of the bracket are bent at ytheir v outer ends in rightangle formation to terminate in inwardly directed projections or ngersI2 to be mounted in holes in the face of the block opposed to thegrooved face thereof, with the result it will beseen that the blocky isamply sup- .ported vwith* respect to the form, so that when the from anywell known material, as Well as may be provided with a groove I3extendinglongitudinally of v.either of the `end faces thereof for use asacornerblochand such a block is shown inFigure 2,v whichlikewiseillustrates that the lgroove I3- .is of the sameshapeas thegroove I and communicates therewith.

The block of the form of Figure 5 is of elongated formation or `in theform of a strip and is made from' any suitable metal for use inprefabricated metal buildings as previously indicated 10 theinnerportionthereof provided withastraght gitudinally in one facethereof, but it will be obvious that the block of Figure `5 may beprovided with like grooves in either or both of itsv ends.

In Fig. 3 I have also illustrated the manner of associating the flashingwith respect to my block and in that gurethe roof boards or foundationare indicated by the reference numeral I5, with roofing material I6 laidthereon in the usual manner, and upturned against the Vwall to providebase hashing l1, itbeing noted that the upturned portions arcorv alength to extend in close proximity to the groove of my block. Thecounterflashing which is indicated by the reference numeral i8 is inthe` form of sheets when used with the blocks as shown in Figure `3, itbeing understood that the blocks are arranged in end to end relationwith the-grooves i in reg. istration for receiving the counterflashing,as will be apparent.

In forming the. counterflashing forr use as shown in Figure 3, thesheets are bent longitudi nally` from end to end laterally beyond thelon- Y gitudinal center thereof to provide an upper portion ia when thecounterflashing is in place as shown, vwith the portion i@ disposed atan upward angle or inclination with respect to the" ood-y portion 20 andarranged Within the groove to rest upon, the inclined lowerlwallthereof, and

the portion i9 is provided` along its-upper edgevvwith a clownturnedflange 2| engaging thefront wall of thefchannel 13 in hooked associationtherewith, as shown. The body portion 2G is-arranged against the baseflashing ofthe roofingmaterial and the lower edge of the hody portionisvoutvturned to provide a ila-nge 2 2.

For cooperating with the `flange 2| to loc the dashing in place withrespect to the groove.

of the block, I provideprecast 'filler strips 23 of expansionmateriaLsuch as asphalt or the like' that are inserted and driven.within the groove to extend into the channel thereof n in hookedformation. uddth to extend outwardly of the groove beyond the flashingfor disposal in overlapping relation The strips 23 are-preferably of avthereto, foramply protecting .the same, as will be apparent uponinspection of Figure 3.

Fromrthe foregoing, it will be obvious that the association of thedashing with respect to the groove allows for ready removal andreplacement thereof, Y but casual removal is practically impossible, andit willbe furtherA obvious that the body portion 20 'holds the baseflashing in lplace against the wall thereby providing a positivelealiproof vjoint at the juncture of the roof therewith. Y

It is thought' from. the foregoing description that the advantages andnovel featuresof the invention will be readily apparent.

`inner channel extending in a plane below the inclined portion, saidchannel having a straight forward wall and a rear wall curved upwardlyfrom the bottom oi the forward wall and merging into j the upper wall ofthe inclined portion in curved formation, a sheet of flashing materialbent to provide a portion disposed at an upward angle to its remainingportion 'and mounted within thegrooveto `rest upon the bottom vwall ofthe inclined portion, a downturned flange'alo-ng the free edge of theangle'portion and disposed Within the channel in engagement with the`straight `forward wall thereof to fasten thesheet tothe block,` withsaid remaining portion paralleling the block for disposal in overlappedrela.- tion to base ashing of roofing material, and a precast asphaltlfiller` strip within the groove and having its inner portion dependingywithin the channel to hold the sheet in'f'astened position and being ofa Vwidth to project outwardly beyond the groove for disposal inoverhanging relation to said remaining portion of the sheet.
